How much is spent in the UK on CCTV?

How much are councils spending on CCTV in the UK? Well a recent report has shown that over 300 million in the last 3 years. The article suggests that this is a huge waste of tax payers money and says that CCTV does not prevent crime? An interesting point of view of course but with all such sweeping statements it is always difficult to prove how much crime CCTV does prevent. It seems that in many serious criminal cases, CCTV is the very first port of call for police looking for clues. Inevitably many crimes are solved because of CCTV as for the argument does it prevent crime? We think that the minute people know that they are not being watched, crime will rise
